Stepanpol® PHN-56

1, 6-hexanediol-neopentyl glycol-ortho phthalic anhydride based polyester polyol. This aromatic prepolymer grade exhibits excellent hydrolysis resistance, very good thermal stability and primary hydroxyl advantage. It provides extended open time and good green strength in reactive hot melt adhesives. Has a very good dispersion characteristic in polyurethane dispersion applications. It delivers enhanced adhesion to a variety of metal and plastic substrates while improving abrasion resistance and overall hardness by using phthalic anhydride as the building block. Used in urethane adhesives, hot melt adhesives, one component foam (OCF) insulating sealants, construction, UV cure, flexible packaging, woodworking, fabric laminating as well as product assembly applications. Its recommended storage temperature is 15-35°C.
